Ontogeny Recapitulates Phylogeny

"Ontogeny recapitulates phylogeny" is a catchy phrase coined by Ernst Haeckel, a 19th century German biologist and philosopher to mean that the development of an organism (ontogeny) expresses all the intermediate forms of its ancestors throughout evolution (phylogeny).   His theory was later proved wrong, but the catch phrase remains.

I'm ashamed to admit that for many years, I had a page of this website that misquoted Ernst Haeckel as having said, "Ontology recapitulates phylogeny".  Then, on June 11, 2004, I received an email from Richard Cranford saying,

Ernst Haeckel most certainly did not coin the phrase "ontology recapitulates phylogeny."  Ontology is the branch of metaphysics that deals with the nature of being.  What Haeckel said is that ontogeny--the development of an individual organism from embryo to adult--recapitulates phylogeny.

Can you see the egg on my face?

I wondered where in the world I could have gotten the ridiculous idea that Ontology was the thing that recapitulated phylogeny, so I did a Google search for the phrase (in quotes), "Ontology recapitulates phylogeny" and, can you believe it?  I got results from 67 different websites (including my own!).  Some of the websites were blogs and message boards, so the website owner doesn't endorse the views expressed on it, and so there's no point in emailing him with a correction.  But I did email many of the others, pointing out the error.

Michael Anton Parker sent me an email asking why this very web page you are now reading skirted all around the fact that Willard Van Orman Quine, the American philosopher, (and not Timothy Leary) invented this corruption of Haeckel's quote.

Mike wrote: It's plain remarkable that your webpage gets so close to touching on this special topic, but gives the impression of innocent unawareness!  Talk about a convoluted affair!  For the record, now that I understand the historical context to Quine's phrase, I find the original version only moderately interesting, while finding my awe at the profundity of Quine's phrase doubled upon realizing such an insight could fit into a shape chiseled for unrelated purposes.

[Isn't that pretty?  No?  Then reread that last paragraph, you ingrate!]

I wrote,

> I think the "ontogeny" quote came first, as part of the now discredited
> theory proposed by Haeckel.

Mike replied: By all means, absolutely, yes. The "ontology" version was a clearly intentional allusion to the 19th century quote reflecting the concerns of 20th century formal philosophy.  I pointed out,

> I have seen the "ontology" quote attributed to Timothy Leary. But a quick

> Thanks for the info.

Mike replied: There's no chance whatsoever the quote is due to Leary. The chronology alone rules it out. Since writing to you, I've verified that Quine himself attributed it to James Grier Miller, but it would appear that the quote's currency owes to Quine's fame and that Quine virtually deserves to get credit for the quote, despite actually acquiring it from Miller. I have no idea who Miller is. I hope to learn more about the matter eventually though.

Here's a partial summary of the websites with this same goof [or, perhaps this intentional or unintentional tipping of the hat to Quine]:

This message, in the Friends of Rohit Khare archive is making a joke, I think.  In any case, the message is all about ontology, and includes a fairly nifty definition of it:

The subject of ontology is the study of the categories of things that exist or may exist.  The product of such a study, called an ontology, is a catalog of the types of things that are assumed to exist in some domain of interest from the perspective of a person who uses some language (natural or artificial) for the purpose of talking about that domain.  The types in the ontology represent the predicates, word senses, or concept and relation types of the language used to discuss topics in the domain.

This very brief biography of Haeckel begins,

In a letter to her son in the 1870s, Emma Darwin, the great naturalist's wife, wrote that a recent guest was "very nice and hearty and affectionate, but he bellowed out his bad English in such a voice that he nearly deafened us."  The guest was Ernst Haeckel.  An early and ardent proponent of Darwinism, Ernst Haeckel worked for a time as a doctor before toying with the idea of becoming a scientist — or a landscape painter.  He ultimately chose science, though his brand of science was highly speculative.

It goes on to criticize Haeckel for his racist ideas, such as the idea that humans comprised 12 species, with one superior to the others.  Can you guess which species Haeckel belonged to?

(the source of the famous phrase, "ontology recapitulates phylogeny"). ...

Disguised as a harsh critique of the Public Broadcasting System's Evolution series, this article presents the "rational" argument (as opposed to the religious one) against evolution.  Cleverly written by a former Reagan speech writer, Josh Gilder, the article takes pains to distance itself from the religious right.  Instead, it points out that Darwin didn't get it exactly right, that efforts to recreate evolution in the lab have failed, and that, like a car engine, a cell has interconnecting moving parts which could not have evolved separately, and which could not have sprung into existence all at once, either.  Modern scientists have uncovered some errors in Darwin's original theory, but these modern ideas are simply not presented in the TV series.  For example, Michael Behe, a molecular biologist at Lehigh University, published a book in 1996 entitled Darwin's Black Box that raised new and interesting theoretical objections to Darwinism.  And, in 2000, U.C. Berkeley Ph.D. biologist Jonathan Wells published his groundbreaking Icons of Evolution, which dismantles the "proofs" of evolution, one by one.

Katherine Crosswhite thanked me for the email I sent her to tell her of this mistake, and went on: I do actually know both of those words, so I am embarrassed to have gotten them mixed up.  I don't know how that happened.  Have you looked for any mistakes in the opposite direction, such as philosophers mistakenly referring to Descarte's "ontogenetic argument"? ("I grow, therefore I am"? ;-)

I replied, no, I didn't search for misuse of ontogeny where the author meant ontology.  But another kind of reverse mistake would be "ontogeny recapitulates phylology".  The only trouble is "phylology" isn't a word.  The closest word is philology. "Ontogeny recapitulates philology" would mean the biological development of an organism parallels the comprehensive study of language, a mistake no sillier than the one you and I both made in our websites.  But there was not a single instance of this twist anywhere in the Land of Google.  Interestingly, there was one website containing the phrase with the non-word phylology -- a deep and pompous tome called A Frozen City of Ideas.

This website is a hierarchically structured book entitled Einstein's God; the Science of Zen. It is a holistic view of human behavior including science, religion and enlightenment organized around a history of social evolution. Mr. Eklund includes this warning: The contents of Einstein's God and the Science of Zen are scientific in the best sense but it contains "new paradigms" that will not be accepted by the scientific establishment for another generation. In other words, and I say this with kindness, he's a crank and he admits it. That puts him head and shoulders above most cranks. Furthermore, although the converse isn't true, most great thinkers were regarded as cranks in their time.

An index of Karl Eklund's other writings can be found at http://www.angelfire.com/ma/karlek/index.html, which has a lot of good stuff, including a photo of the author.

This blog gives a high school girl's view of life, including an encounter with a fox on an over-watered suburban lawn, and her theories of the evolution of dancing.  After I brought this "ontology" error to her attention, she called me "Sir", which cut me to the quick.  She continued, "I know the difference between ontology and ontogeny.  It was a simple flub, as when somebody as miscegeny when meaning misogyny."  I replied in a way I hope was kind, saying, in part that I did enjoy reading the blog.  I pointed out that if she wants to start a pseudo-scientific journal, she'll have to compete with uk.arxiv.org, which is already in existence.  By the way, I couldn't find miscegeny in any dictionary.  However, the dictionary of obscure words defines "miscegene" as a "person of mixed racial heritage".  So would I be right in guessing that miscegeny is the practice of bringing into the world persons of mixed racial heritage?

I never received a reply from the girl who wrote the blog, but John, an attorney researching miscegeny laws wrote,

I enjoyed your page on ontogeny vs. ontology ... I think you might find it interesting that I found your site with a google search involving "miscegeny."  I think that it is interesting that this page of your web site is high in the google returns for the word "miscegeny.".  I am an attorney in Louisiana and I was specifically doing a little research into out miscegeny laws ... interesting how miscegeny is indeed mistaken for misogyny.  It happen a lot!  Again, I enjoyed your web site.

John

I replied,

Yes, I do find it interesting (and fun) that my website is high in the ranking for this and various other obscure words.  This particular word, miscegeny, ranks me pretty high because, as near as I can tell, it's not a word.  (If it were a word, I theorize it would mean "the practice of bringing into the world persons of mixed racial heritage".  I guess there are laws against this in some states.)  Other non-words in my website, such as "hunnerd", rank me pretty high, too.  My website has been around for almost a decade now, and many of its pages are so full of "crap" that many people link to them with titles like "click here for a really uninformed opinion on gun control" and the like.  This, and the fact that the site contains way over a thousand pages, with more added weekly, tends to make me rise in the rankings.  Being linked-to is like publicity: say anything you want, but spell my name correctly!  Almost all the people who visit my site come from Google.  Three years ago, yahoo was my biggest referrer.  Three years before that, it was altavista.  (I still remember the days when altavista was altavista.digital.com, which truly dates me in the Internet age, since Digital has since been swallowed, twice, by bigger fish Compaq and then HP.)  Queries for obscure things bring thousands of people every day to my site, which makes me almost famous in an obscure sort of way.  I estimate that about 0.1% of the people who visit my site send me an email, which I always appreciate.  I appreciate this email you sent me almost as much as I appreciate the ones that say I am a [biological function deleted] [anatomical reference redacted] [lifestyle preference excised]!

This website got the phrase right, "ontogeny recapitulates phylogeny".  In other words, the website continues, the developing human fetus goes through stages of development which mirror the development of the human species, taking on various forms such as tadpole-like, to reptilian, to monkey-like and so on.  Timothy Leary adapted this quote to say 'ontology recapitulates phylogeny', that is, that the development of an individual's world view (ontology) mirrors the development of the species."

I was not aware that Timothy Leary used the word Ontology intentionally in a corruption of this famous piece of misinformation.  I must say the use of the word "ontology" to mean "world view" is really quite a stretch. According to Digital Polytheism, by Timothy Leary and Eric Gullichsen, ontology recapitulates theology, which means our understanding of knowledge parallels the study of God and his relationship to man.  Maybe Timothy Leary said both things.
